Installing & Removing B-Model Cowl With Prop Installed

[Area 51%]

I still have a nasty oil leak on my engine that I will have to address further next spring. I suspect a leak around a case saver but have to get some adjustable pushrod tubes so I can get the super tin out of the way to see what's going on while the engine is running. I'm tired of pulling the head off every time I thought I had it fixed and didn't.

Are you planning on using the adjustable pushrod tubes for just testing purposes, or will you be keeping them in place? The reason I ask is I had an interference issue between the back two pushrods and overly radiused tube ends. The tubes were cutting into the pushrods.
I solved that problem with adjustable tubes, so I didn't have to remove the heads, but I had to grind quite large clearances in the super tin to clear the tubes. Not all tubes are created equal. I guess I got the "fat" ones.

My intent was to just use them for testing purposes since there are mixed reviews on oil leaks caused by them as well. The stock tubes that came with the engine seem to be doing fine. I just make sure I re-expand them a bit before I re-install them. But...if the adjustable ones don't leak after a couple of runs, I'll leave them in.
